A CORPORATION OF srnnL-woon mcnnvn Application filed February 3, 1927. Serial No. 165,545.

Our invention relates to steel wool ma? chines.

It is the object of our invention to rovide means for maintaining wire from w ich steel wool is made in proper engagement with the driving sheaves and in such form- .ing in the direction of the arrow; and

igu're 4 is an end elevation looking towards the machine from the outside thereof. Referring to the drawings in detail, lis a table carried by a frame 2. 3 indicates the cutting tools. The wire is a single continuous strand 4 looped over the sheaves 5 and 6 which are pivotally supported in the frame 2. The wire is unwound from one supply drum 7 and taken up by the other supply drum 8.

The details of this arrangement are fully set forth in the patent to William H. Robbins, No. 1,584,145, dated May 11, 1926.

The particular invention now involved deals with the use of spring-pressed rollers for maintaining the wire in position on the driving sheaves. Under some conditions of use, it is desirable to employ this improvement of the spring-pressed rollers.

9 indicates a roller adapted to engage with the wire 4 as it comes upon the drum, or as it departs, such roller being supported pivotally on an arm 10 pivoted at 11 on a bracket" A lar er and broader roller 15 is mounted ,on the ever 16 engaging the remainder of the wires or so closely adjacent to them as to' prevent them from moving off of-the sheave 5 or 6. This lever 16 is pivoted at 11 on the bracket 12 and is held in position by a spring 17 which is attached to the free end of the lever 16 and to the frame 2.

additional means adapted to engage the re- We find it desirable to mount the roller 9 adjacent the point of departure or arrival ofthe Wire 4 on the sheave 5 or 6 and to mount the roller 15 adjacent the arrival and departure of the loops of wire on the sheave 5 or 6, so that the pressure may be applied between the axle 18 supporting the sheaves and the roller 15, so arranged that the wire is firmly supported beneath the roller 15 and the pressure by the roller is directly over the axle center or as near thereto as practicable.

It will be understood that we desire to comprehend within our invention such modifications as may be necessary to adapt it to var 'ng conditions and uses. F

aving thus fully described our invention, what we claim as new and desire by Letters Patent, is: 1. In a steel wool machine, driving sheaves, a wire loo (1 over said sheaves, take-up and supply rums for said wire, and yielding means for maintaining said wire in engagement with said sheaves, said yielding means being adapted to engage the wire with respect to each sheave as it enters upon the sheave or departs therefrom, and an maining loops of the wire on the sheaves adjacent each sheave, said means being adapted to be held in (yielding engagement with said wire so loope 2. In a steel wool machine having power driven wire, driving and supportin sheaves and take-u means for the free en s of said wire, a re atlvely narrow roller yieldingly en'gaginx the departing and arrivin portions 0? the wire ad acent each 0 said sheaves, and a broad'roller yieldingly pressed in engagement with the surfaces of the loops 'of said wire on said sheaves over each sheave WILLIAM H.
